Additional Notes

The DE3423 is the most frequently specified glove box bulb across the Kia Sorento lineup, appearing in model years 2003-2009 and 2018.
The DE3423 follows the ANSI standard recognized in the United States and Canada, making it a widely available festoon-type bulb with a 41mm length and end-cap contacts operating at 12V.
Festoon bulbs make contact at both ends of the housing rather than through a side-mounted base, which is a defining characteristic of the DE3423's physical installation method.
The 2020 Kia Sorento uses the 12961 bulb, a Philips-designated miniature wedge type with a T10 form factor and a W2.1x9.5d base, rated at 12V and 5W.
The T10 wedge base of the 12961 is mechanically incompatible with the end-cap festoon socket used by the DE3423, meaning the two bulb types are not interchangeable despite sharing the same 12V operating voltage.
The W2.1x9.5d base designation on the 12961 refers to a specific wedge pin configuration, where the numbers describe the contact width and insertion depth standardized for that bulb family.
The DE3423 and 12961 represent two distinct socket designs present across the Sorento's production history, and using the incorrect type risks either a non-fit or potential socket damage.
